OAKUM SEAM-CALKIN G TOOL.

Specification of Letters Batent.

Patented Mar. 11, 1919.

Application filed July 3, 1917. Serial No. 178,450.

To all whom it may concern:

Be it known that I, JAMES E. GiLMoRE, a citizen'of the Dominion of Canada, residing at Prince Rupert, in the Province of British Columbia, Canada, have invented certain new and useful Improvementsin Oakum Seam-Calking Tools, of which the following is a specification.

This invention relates to a tool for call:- ing the seamsof any ship or craft where wood is used for hull or deck, the tool being adapted for use with a pneumatic or any power-operated hammer. In calking such sea-ms with the tool commonly used for such purpose the tool penetrates the seam to such a depth that the operator cannot disengage it .to move it along the seam while it is exposed to the percussive action of a pneumatic or other power hammer.

This difliculty I overcome by using a rotata'ble calking disk, the edge of which is in cross section shaped to the form of the various ca'lking tools used. A pair of these "disks are mounted tandem-wise in a frame having a percussive head on which the blows of a power hammer may be delivered, so that the tool may be moved along the seam while it is being struck by the hammer. Provision is also made by which the axis of the percussive head may be endwise moved on the frame that agreater impact may be delivered more directly to one wheel or the other where thegreatestcalking resistance is experienced.

There are several other features of importance to the satisfactory working of the device to which attention is drawn in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a side elevation of the device.

Fig. 2, a plan of the same.

Fig. 3, a vertical section on the line 3-3 in Fig. 1.

Fig.4, a vertical section. on the line 47-4; in Fig. 1.

Fig. 5 is a cross section of the frame showing the pin connection of the guide fences thereto, and r r Fig. 6 is a plan of the guide fences in front of one calking wheel.

The device comprises a pair of steel disks 2 and 3, the edges of'which are in cross section shaped to the requirement of use in layering and calking the oakum or other calking material into a seam. These calk: ing wheels 2 and 3 are rotatably mounted tandem-wise in a frame 4: in a manner that they are readily removable to enable wheels of different cross section to be used as .required. I

Secured to the upper side of this frame 4; midway between the wheels 2 and 3 is a percussive stem 6, the attachment being such as will permit a limited longitudinal movement of the stem on the frame to permit the axis of it to be moved nearer to one or other of the axles 5 of the wheels 2- or 3 as required. The percussive head is here shown as divided in the plane of the calking wheels to straddle them and have a well distributed bearing on the frame 4 on each side and is secured by a bolt 7 through an elongated slot 8 in a downward exten sion from each side of the percussive head bearing on the frame 4. This bolt connects the percussive head to the frame and se-.

cures it in any desired position of adjust ment thereon. p

The stem of the percussive head hasa handle sleeve 9 mounted on it by which the device may be held in the hand of the user without receiving the shock of the blow. On this handle provision for controlling the power hammer may be mounted, but such is not material to the subject mat- 'ter of this application. Another handle 10 is pivotally' mounted on a pin 11 at the back end of the frame' l in a manner that byntightening the bolt or pin the handle may be secured in any, position of angular adjustment to suit the convenience of the 'of the frame 41 in advance of each of the 'calking wheels 2 and 3, each fence being independently connected to the frame 4:. by pins'13 upwardly projecting from the fence and vertically movable in the sidesof the frame. The headsof these pins 13 are on the upper side ofthe frame t and the fences are normally held at the lower limit of their movement by a spring 14 coiled on each pin between the fence and the underside of the frame. r r

The leading ends of these guides are out- 5 wardly flared from the line of the seam, as shown in Fig. 6," to collect and retain the calking material in the line of the seam where it will.be engaged by the calking wheels. f r The holes in which the pins 13 are endwise movable in the frame 4: are laterally enlargedoutward toward the underside, as shown in Fig. 5, to permit the fences a certain amount of lateral movement outward against the V resistance of their springs, which tend to hold them toward the line of the seam.

To guide the calking disks in the seam being calked, seams 15 are removably attached to project at right angles from each end of the frame'on either side. A spare calking wheel 17 is mounted on the end of each stem between collars 16 which are adjustable on the stem that the guide wheels may be set to the distance of the seams apart. 'In use, the calking wheels 2 and 3 are applied to the seam to be ca-lked with the guide .wheels '17 in the next open seam, and the percussive hammer being applied to the. end of the stem 6, as the blows are delivered the tool is rolled along the seam. The springcontrolled fences 12 bear on the faces of the planks and while permitting the calking wheels to penetrate the seam resiliently guide the oakum or other calking material into the plane of the wheels. As the tool is advanced along the seam provision may be made between the wheels 2 and 3 or in front of each of them for applying oil or grease to the edges of the calking wheels to prevent them binding in the seams.

The device constitutes a' convenient tool enabling the modern pneumatic or other power hammer to be applied to calk the seams of wooden-built vessels, or the wooden decks of steel ships. j

I do not desire to be confined to the particular construction here set forth as the same may be modified within the scope of the following claims which set forth what I desire the protection of Letters Patent 011.

1. A tool for calking the seams between the boards of the hull or the deck of a vessel, said tool comprising a disk, a frame in which said disk is rotatably mounted, a stem shiftably connected to said frame, whereby the I position of said stem alongsaid frame may be changed to vary the force of impact with relation to the axis of the disk.
